Turn Based (TB) - Speaks for itself, a system of RPing where everything from casual talk to intense fighting occurs. Everything is, believe it or not, based on TURNS. This can be bent some during casual talking some. Before a spar, or fight players must pick an order in which to post. There are many different types of TBing, a few listed here.
TBL - Turn Based Literate. A turn based RP in which posts include much detail
TBR - Turn Based Reality. A turn based RP in which all occurances, object, and actions are realistic, NOT fantasy, real swords, guns, and so on.
TBOP - Turn Based Out Post. A turn Based RP in which one player tries to make a post longer than the person before them, if they fail to do so, they lose.
Speed SIM, Speed Simulation (SS) - Mainly used for fighting, occurs in no order whatsoever. Fighting styles rely on Attack-confirm techniques. One player posts an attack, the other must dodge it with a longer post than the first person. This needs to be done before the first person makes a post confirming their ttack that ALSO must be longer than their attack post. I understand this will be akward (er whatever) for this type of posting system, but you must stay alert (remember to refresh the page)
